Hello new followers! I am a curious cognitive scientist, with a background in semiotics, a strong focus on quantitative and computational methods and meta-science and scattered interests in how we think, learn and function through conversations.

For a taste of my work, a thread of threads: 1/

In Ch 19 (nyu-cdsc.github.io/learningr/as...) of his 2nd edition, Kruschke used *residual* SD as a standardizer for group differences from a multilevel ANCOVA. Is there any precedent for using a *residual* SD as a standardizer for a standardized mean difference effect size? #RStats

because the internet can still be fun, I found out that this was a swiss watch meant for the US marker (uncalibrated, to avoid US tariffs (ah!) on precise watches, apparently), and more recent than it looks, but mimicking older styles.

The kids’ find of the day was my great great grandfather’s clock in silver. About 40 years ago I inherited it, it didn’t work and I tried to open it to fix it. Still open since and not working :-)

🫁❤️New preprint out: The social, decoupled self

We show effects of interpersonal synchronization of physiological rhythms on intrapersonal cardiorespiratory coupling: when we sync our breathing, our breathing–heart rhythms decouple, with a perturbed phase-relationship

thanks! very interesting indeed! :-)

Oh, super cool! So, you’d imagine language mix specific cues/strategies? So that’d eg be different in Vanuatu? Or do you think there could be more generalizable curs?

How do multilingual babies acquire their languages? In Africa, multilingualism is the norm. In our new study with 9-11 month old Ghanaian babies learning up to 5 languages simultaneously, we found that they were able to recognize words in text passages in Akan, one of their languages.

Was asked about collinearity again, so here's Vahove's 2019 post on why it isn't a problem that needs a solution. Design the model(s) to answer a formal question and free your mind janhove.github.io/posts/2019-0...

tl;dr

Collinearity is a form of lack of information that is appropriately reflected in the output of your statistical model.
When collinearity is associated with interpretational difficulties, these difficulties aren’t caused by the collinearity itself. Rather, they reveal that the model was poorly specified (in that it answers a question different to the one of interest), that the analyst overly focuses on significance rather than estimates and the uncertainty about them or that the analyst took a mental shortcut in interpreting the model that could’ve also led them astray in the absence of collinearity.
If you do decide to “deal with” collinearity, make sure you can still answer the question of interest.

Happy to see this work published in Psych Review. It's an impressive and important bit of theory/modeling about how we learn about decision-making under risk. Here's a slide with the super-coarse-grained summary of our results. Read the paper for (much) more. osf.io/preprints/so...

Modeling the evolution of peer and vertical/oblique learning strategies for gambles under uncertainty
We recover many empirical results and generate new hypotheses:
Worse conditions lead to more pessimistic behavior
Younger people are overly optimistic
Wealthy people can afford to take more risks
Payoff-biased learning for the rich, parochialism for the poor
Poor people may be slower to adapt to environmental change, creating the appearance of “poverty traps”

Simulations are no longer just “nice to have.” They’re reshaping how we do statistics.

This one of the many papers coming out of eSymb (which was masterminded by Kristian Tylén) in which we use cogsci experiments as counterfactual setups: what if the world was (simplified) like this? how would the results resemble (or not) the very sparse archeological records?

Riccardo Fusaroli @fusaroli.bsky.social · 23d

We weave in multiple threads of evidence and suggestions from other domains (practicing what we argued in link.springer.com/article/10.1...) and theorize that these choices involved the complex interplay of perceptual, technical (production), and cultural factors. Read more on that in the paper! 9/

These findings suggest that the choice of side views and the use of abbreviated outlines in Paleolithic art were more complex than just an issue of optimizing recognition or universal aesthetic preferences. 8/

Key finding 2: complete outlines were consistently better than abbreviated ones (showing just head-neck-dorsal line) for both recognition and aesthetic appeal. 7/

Key finding 1: Side and oblique views performed equally well for recognition and aesthetics (as predicted by ecological psychology), outperforming frontal and rear views. This suggests cave art was not simply optimizing for recognition 6/

Riccardo Fusaroli @fusaroli.bsky.social · 23d

Traditional views (aka often found in the literature) would say that side views are superior to all others to convey the info necessary to recognize the animal species, while abbreviated outlines could emphasize on salient features (recognizability) and just look nicer (aesthetic appreciation) 5/

We tested how different viewing angles (frontal, oblique, side, rear) and outline styles (complete vs. abbreviated) affect both animal recognition and aesthetic appreciation among modern participants. 4/

We started from an ecological approach to vision. Instead of seeing perception as your brain crunching a static image, it's about detecting information from the world to guide action. A line drawing works if it provides the right kind of information. 3/n

TL;DR: Side & oblique views contain > info for recognizing an animal, but the former are easier to draw. Abbreviatons are harder to parse & less aesthetically pleasing, suggesting their use was likely driven by cultural convention & the practical need to draw quickly in low-light environments. 2/n
